The company at Battersea are First City Air and the Maroon Gazelle of which you talk is G - MANN, recently seen at Thruxton, not sure if it lives down there or what.
There is one guy who owns a private strip near Maidenhead, who has put in a very strange request to increase his current fixed wing movements to include helicopters. Not sure of the figures, but it is a very big increase. There is rumour circling that he may be buying them, and is pretty sure that he will get them. Anyone know anymore, as all I have is rumour.
